WIND ROSES –

Each Wind Rose shows the strength and direction of the prevailing winds in the area and month. These have been recorded over a long period of time. In general, the lengths of the arrows indicate how often the winds came from that direction. The longer the arrow, the more often the winds came from that direction. When the arrow is too long to be printed in a practical manner, a number is indicated. The number in the center of the circle shows the percentage of the time that the winds were calm. The lengths of the arrows plus the calms number in the center add up to 100 percent. The number of feathers on the arrow indicates the strength of the wind on the Beaufort scale (one feather is Force 1, etc.). Wind Roses are taken from Pilot Charts.

In this example, moving around the circle clockwise, we can see that about a third (34 percent) of the time the winds came from the east; about 15 percent of the time (the length of the arrow is roughly about the diameter of the circle) from the SE, Force 4; about 10 percent from the south, Force 4; rarely from the SW, West, and NW (about 3 percent each x 3 = 9 percent), Force 4; about 10 percent from the north, Force 4; about 20 percent of the time from the NE, Force 4. It was calm 2 percent of the time. That is a total of 100 percent. For a more complete explanation of Wind Roses, go here.
